We have a both a tilt head and lift bowl KitchenAid Stand mixer and they get used pretty heavily. As long as we pair the proper mixer to the task, we get by. The big issue I have is with the flat beater attachments. First and most important, it is aluminum so even a immaculately clean and polished beater gives our whitest cakes a grey cast to them. The second is that they don't mate very closely to the bowl so there is quite a bit of stopping to scrape down.
